you were just 6yrs old when you and jungwon became best friends because your mom's are close

You were very close with jungwon until he moved in another country because of his mom's work when you were 8yrs old

Few years past and you were now 16 but you still haven't seen him

While you were walking in the park alone you suddenly bumped into someone who was wearing shades

After he removed his shades you suddenly said"jungwon?",he responded "how do you know my name?"
